NAMEglVertexPointer - define an array of vertex data
CSPECIFICATION
void glVertexPointer( GLint size,
GLenum type,
GLsizei stride,
const GLvoid *pointer )
PARAMETERSsize Specifies the number of coordinates per vertex;
must be 2, 3, or 4. The initial value is 4.
type Specifies the data type of each coordinate in the
array. Symbolic constants GL_SHORT, GL_INT,
GL_FLOAT, and GL_DOUBLE are accepted. The initial
value is GL_FLOAT.
stride Specifies the byte offset between consecutive
vertexes. If stride is 0, the vertexes are
understood to be tightly packed in the array. The
initial value
is 0.
pointer Specifies a pointer to the first coordinate of the
first vertex in the array.
DESCRIPTIONglVertexPointer specifies the location and data format of an
array of vertex coordinates to use when rendering. size
specifies the number of coordinates per vertex and type the
data type of the coordinates. stride specifies the byte
stride from one vertex to the next allowing vertexes and
attributes to be packed into a single array or stored in
separate arrays. (Single-array storage may be more
efficient on some implementations; see glInterleavedArrays.)
When a vertex array is specified, size, type, stride, and
pointer are saved as client-side state.
To enable and disable the vertex array, call
glEnableClientState and
glDisableClientState with the argument GL_VERTEX_ARRAY. If
enabled, the vertex array is used when glDrawArrays,
glDrawElements, or glArrayElement is called.
Use glDrawArrays to construct a sequence of primitives (all
of the same type) from prespecified vertex and vertex
attribute arrays. Use glArrayElement to specify primitives
by indexing vertexes and vertex attributes and
glDrawElements to construct a sequence of primitives by
indexing vertexes and vertex attributes.
NOTESglVertexPointer is available only if the GL version is 1.1
or greater.
The vertex array is initially disabled and isn't accessed
when glArrayElement, glDrawElements or glDrawArrays is
called.
Execution of glVertexPointer is not allowed between the
execution of glBegin and the corresponding execution of
glEnd, but an error may or may not be generated. If no error
is generated, the operation is undefined.
glVertexPointer is typically implemented on the client side.
Vertex array parameters are client-side state and are
therefore not saved or restored by glPushAttrib and
glPopAttrib. Use glPushClientAttrib and glPopClientAttrib
instead.
ERRORSGL_INVALID_VALUE is generated if size is not 2, 3, or 4.
GL_INVALID_ENUM is generated if type is is not an accepted
value.
GL_INVALID_VALUE is generated if stride is negative.
